GRAIN-D063 FOR CARS.

Specification of Letters Patent.

Patented April-'7, 1908.

Application filed August 26, 1907. sem No. 390,138.

To all whom it may concern:

, Be it known that I, JOHN EDMAN,-'a citizen. of the United States, residing at Minneapolis,

in the county of Hen epin and State of Minnesota, have invented cert'ain-new and useful Improvements'in Grain-Doors for Cars; and I do hereby declare-the followin to be a full,

clear, and exact description of t e 'invention,.

such as will enable others skilled in the art to which-it appertains tomake and use the same.

resent invention relatesi to (grain doors ..the general character disclose and claimed in my prior patent No. 856,775, is.- suedof date June- 11, 1907, entitled gram 1: doors for cars]? In some respects, also, the

construction herein illustrated has features similar to those illustratedand claimed'in my pending application N 372,494; filed May 8, 1907,'--entitled grain doors for cars. v

: In the accompanying drawin s which ilhfstrate the resent invention, li e characters.

indicate h e parts throughout the several views.- I

Referrin to these drawings; Fi ure 1 is a de elevation showing t e'central portion of a car body having my improved grain door applied thereto. Fig. 2 is a vertical section t ken on the line x rhof Fig. 1,

some parts be ng broken away. Fig". 3 is a g 1:. horizontal section taken on the line at m of Flg. 1; and Fig.4 is a detail in vertical section taken on the line 11; x of Fig. 1-,'so1ne parts being broken away, and the parts shown being'on a-"larger scale than in the it. other views.

The numeral 1 indicates a car bodyhavin at its sides the usual door opening formed between posts '2. inner edges of the door posts 2 are sto e cleats shown as formed by channel-shaped -metal bars 3 that extend preferably about one-half 'way up the said-door posts. A

short distance from their projecting edges,

the stop cleats 3 are. shown as provided 5 with outwardly projecting door retaining flanges 3*.

Located adjacent to the inner edge: of the door posts 2 and just outward of the cooperating stop cleats 3 are vertically disposed oscillatory sha'fts shown in the form of tubes. 4, and provided with radially and longitudinally extending lock blades 5. At their upper ends, the tubular shafts 4 are j ournale on hubs 6 secured to the to of the i. door frame, and at their lower ends t ey are mental door section 10. The hinges 9 1;

an outwardlyl 16, which, W

Rigidly secured to the -'ournaled in suitable seats formed in the ottom of the door. frame. a The grain door is made up. of ripple lower main door sections 7 and 8, t a connected by hinges 9, and a loose su and t are P the outward movement of the doorsection 8 to a vertical position with respect to the door'sect-ion7, but permit the same to be folded inward thereon. The lower door secas tion 7 is clampedv against the stop cleats 3'- by the 'lock blades 5 ofthe shafts 4, All of theasaid door sections are normall held against the inner surfaces of the lock lades. Rigidly secured to the intermediate portion 7 of the door section 7 on the outer side thereof is a lock bracket 11 havin a laterally offset portion 12-, the upper e ge of which terminates in a perforated lock lug 13.

To the intermediate portions of the lock-7'5 blades 5 look bars'14 are pivotally connected at their outer ends. These look bars 14 of such length that when the lock-blades 5 are in normal or locking positions, the free ends of said. lockv barsare adapted to be; turned into the seat formed between the door section 7 and thepflset portion 12 of the lock bracket 11.

To the. central portion of the door section 8 is inte'rmediately pivoted a long-lock lever 15, the lower end of which is provided with extended perforated lock lug en the lever is turned in a vertical position, as shown in the drawin s, is

adapted to closely engage the inturne, free ends of the lock ar's 14and hold, the same interlockedwith the said lock bracket. When the lock'bars are thus held interlocked with 1 the said lock bracket, they hold the lock blades 5 pressed against the door sections. i The upper end of, the lock lever 15-is adapted to beturned into engagement with a seat 17 formed in the top of the door frame. On the central portion of the door section 10 is a lock bracket 18 having an offset end with which the h per portion of thelock bar 15 is adapted to e engaged when .turned into a vertical position, and thereby holdthe said door section 10 in its workinj position. ,A lock bolt or pin 19 is adapt I through the perforations of he look lugs 13 and 16 so as to thereb' hold the lock lever 16 in its operative or ocking position The lower end of this look bolt or pin I'J is perforated so that, if desired, a car seal may be" 110 to be passed I a pair of 1 oscillatory door "scribed.

assed therethrough to thereby hold the said doltaorpin against displacement, and, hence, seal the car door.

The door above described, while especially adapted for use as a grain door, may, nevertheless, be generally used, and when used,

makes unnecessary the use of an outside car door. Any suitable provision may be made such, for instance, as in my prior patent and a plieation above identified, for guiding" t e door sections to and from moperative positions in the top of the car. The door is of small cost, and highly efiicient for the purposes had in view.

What Iclaim is:

1. The combination with a "car bod of a grain door seated in the door 0 ening t ereof, coking blades mounted at the sides of the door opIening,

lockbars extending from said lock lades,

.and means for locking the ends of said lock bars to said grain door, substantially as delades and engageable with'said'lock'bracket at their free ends, and alock lever pivoted to an upper portion of said grain door, the lower end t above said lock bracket, and the upper end thereof being arranged for loc engagementwith the up r portion of the door frame, substantial 3. The combination-with a w bcd havposition, a loc ing a door opening, of a ereofflueing movableinto a position. immediately ing a door opening, of a grain door made up of upper and lower sections seated in said door-opening, a lock bracketon the intermediate portronof the lower door. section, oscillatory lock blades mounted in said door. openin -at the opposite sides thereof for nor mally oldin said grain door ,in' working lever intermediatel-y pivote to the u ,per doorsection and its upper and arrange for interlockin en agernent the seat in the top of the oorirame and having a flan ed lower end, and a lock bolt or in for loficing the flanged lower end of said ock lever to the lock bracket on said lower door section, substantially as described, I 4. The combination with a car body havain door madeu of three sections, 'oscil atory lock blades mounted in said door openin at the v0 posite sides thereof for normally olding the sections of said grain door in working position, a

lock bracket applied to the intermediate portion of the lower door section, lock bars pivoted to said lock blades and engageable with said lock bracket, a lock lever inter mediately ivoted to the intermediate door section an havin with its upper en arranged for interlocking enga ement with the top of the door frame.
